Ingredients
- 2 pounds fresh plums (about 6-8 medium plums), washed, pitted, and quartered
- 3 cups granulated sugar
- 1 tablespoon fresh lemon juice
Step-by-Step Instructions
- Place the prepared plums and lemon juice into a large, heavy-bottomed pot or Dutch oven.
- Cook over medium heat, stirring occasionally, until the plums begin to break down and release their juices, about 10–15 minutes. Mash gently with a potato masher or the back of a spoon to achieve your desired consistency.
- Stir in the granulated sugar until it is completely dissolved. Ensure there are no sugar granules remaining on the bottom of the pot before proceeding.
- Increase the heat to medium-high and bring the mixture to a rolling boil, stirring frequently to prevent scorching.
- Continue to boil vigorously, stirring often, until the jam reaches the setting point. This usually takes between 15 and 25 minutes, depending on the water content of the plums. Test for set frequently (see Expert Tips).
- Once the jam has set, remove the pot from the heat. Skim off any foam that has risen to the surface using a large spoon.
- Carefully ladle the hot jam into sterilized jars, leaving about 1/4 inch headspace at the top.
- Wipe the rims clean, affix the lids and bands (“fingertip tight” if water bath canning, or just sealed if storing in the refrigerator). Allow to cool completely before checking seals or storing.
Expert Tips / Pro Tips
- Testing for Set: To check if your jam has reached the setting point (usually around 220°F or 104°C), place a small spoonful of jam onto a chilled plate that has been in the freezer for five minutes. Return the plate to the freezer for one minute. Push the jam with your finger; if the surface wrinkles, it is set.
- Use Ripe Plums: The flavor and pectin levels are highest in perfectly ripe plums. Avoid underripe fruit, as it may result in a runny jam.
- Prevent Burning: When cooking jam on high heat, stir constantly, especially as it thickens. A thick layer of sugar can easily burn on the bottom of the pot.
- Jar Sterilization: Properly sterilize your jars before filling by boiling them in water for at least 10 minutes, or run them through a very hot dishwasher cycle right before filling.
- Pectin Note: Plums naturally contain a good amount of pectin, which is why this Easy Plum Jam Recipe often doesn’t require added commercial pectin. The lemon juice helps activate the natural pectin.
Variations & Substitutions
- Spice It Up: Add 1/2 teaspoon of ground cinnamon or a pinch of ground allspice during the last 10 minutes of cooking for a warming flavor profile.
- Vanilla Infusion: Add one vanilla bean (split lengthwise) to the fruit while cooking; remove before jarring.
- Other Fruits: This recipe works wonderfully with a mix! Substitute half the plums with ripe peaches or berries like raspberries.
- Sugar Reduction: If you prefer a less sweet jam, you can cautiously reduce the sugar to 2.5 cups, but you may need to increase the cooking time significantly or employ commercial pectin to ensure a proper set.
Serving Suggestions
This versatile plum jam is delicious in countless ways:
- Spread generously on warm biscuits, scones, or thick slices of buttered toast.
- Use as a filling for thumbprint cookies or layered cakes.
- Swirl into plain Greek yogurt or cottage cheese for a fruity breakfast boost.
- Serve alongside a cheese board, particularly with Brie or sharp cheddar.
- Use as a glaze for roasted pork tenderloin or duck breast during the last few minutes of cooking.
Storage, Freezing & Reheating
For properly sealed jars using the water bath canning method, the jam will remain fresh in a cool, dark pantry for up to one year. Once opened, store the jar in the refrigerator and consume within 3–4 weeks.
If you prefer not to can, store sealed jars in the refrigerator for up to 3 weeks. Jam can also be frozen in freezer-safe containers for up to 6 months; thaw overnight in the refrigerator before serving.

FAQ
How long does it take to set?
The setting time varies greatly depending on the specific plum variety and heat level. Generally, it takes between 15 to 25 minutes of active boiling after the sugar is dissolved. Always rely on the frozen plate test rather than strictly timing the boil, as plum water content can fluctuate.
Do I need to peel the plums for jam?
No, peeling is optional. The skins of most plum varieties break down nicely during cooking and add beautiful color and texture to the finished jam. If you prefer a very smooth jam, you may choose to peel them, but it is an extra, unnecessary step for this recipe.
Can I use artificial sweeteners instead of sugar?
While you can substitute some sugar, jam relies heavily on sugar for its texture (setting) and preservation. If you dramatically reduce or replace the sugar with non-sugar sweeteners, you must use commercial pectin specifically designed for low-sugar preserving, as this simple recipe requires sugar for pectin to gel.
Easy Plum Jam Recipe
Ingredients
Method
- Prepare the plums: If using slightly firm plums, chop them roughly. If using very ripe plums, they will break down easily. Place the prepared plums and the lemon juice into a large, heavy-bottomed pot or Dutch oven.
- Macerate and start cooking: Stir the sugar into the plums. Let the mixture sit, stirring occasionally, for about 30 minutes to allow the sugar to draw out the juices (maceration). After macerating, bring the mixture to a boil over high heat, stirring constantly to prevent scorching.
- Boil and reduce: Once boiling, reduce the heat slightly to maintain a steady, rolling boil. Add the optional tablespoon of butter to minimize foam. Cook for 30 to 45 minutes, stirring frequently, especially near the end, until the mixture thickens substantially and coats the back of a spoon.
- Test for set: To test for a set point, place a small plate in the freezer. Drop a teaspoon of hot jam onto the cold plate. Return it to the freezer for 1 minute. Push the jam with your finger; if the surface wrinkles, it has reached the setting point (approximately 220°F or 104°C).
- Jar the jam: Remove the pot from the heat. Skim off any remaining surface foam with a spoon. Carefully ladle the hot jam into sterilized jars, leaving about 1/4 inch headspace. Wipe the rims clean and seal with lids and bands.
- Process (Optional for long-term storage): For shelf-stable jam, process filled jars in a boiling water bath canner for 10 minutes, adjusting for altitude. Let cool completely on the counter before checking seals.
